Question

How much pressure is needed to break an egg if applied from top and bottom?

Answer 1

They do, as long as the egg resists. Imagine pulling a spring by the extremities. The forces cancel out in the sens that the spring doesn't globally move in one or the other direction, but this doesn't mean it stretches.

Answer 2

Answer:

Usually, it takes a little more than 5 ½ pounds of force to crack an eggshell — much less than the weight of a human being — but the precise amount of force needed depends on the direction in which that force is applied and how much the force is distributed (or not) over the surface of the shell
